Hi guys, I'm having some problems with the discrete Transfer Function block. I'm trying to recreate the TF behavior I'm getting from Matlab, but I'm nowhere near. I have tried using both the Polynomial and the Poles and Zeros option to enter the values, but the output remains the same. z^4 - 3.753 z^3 + 5.272 z^2 - 3.286 z + 0.7666 / 4.421e-07 z^4 - 4.333e-07 z^3 I've attached my Embed file, that contains the Reference and the TF blocks. I've also included a couple of screenshots from Matlab that show the behavior I'd like to obtain from Embed. I've made sure that Embed and Matlab have the same Time Step, which you'll be able to see from the reference input (it's the same on both softwares). I don't know what else to do, I really hope you can help me out. Bezier_test.vsm
Hi, I have read the Optistruct User Guide and I have some issues about this two parameters. It says that DISCRETE corresponds to (p-1) in the formula K(rho)=rho^p*K of the SIMP method. After that, it says: "When minimum member size control is used, the penalty starts at 2 and is increased to 3 for the second and third iterative phases." So my question is: when I run an optimisation with MINDIM on, Optistruct automatically sets DISCRETE=3 and DISCRETE=4? So trying to run an optimisation with MINDIM on and DISCRETE equal to a number I decide, is a nonsense? Can anyone answer this question? Thanks!
